Location of EDS-observable GAEA-LC galaxy populations in the [O III]/Hβ versus [N II]/Hα BPT diagram, divided into redshift bins 0.9–1.2 (top row), 1.2–1.5 (middle row), and 1.5–1.8 (bottom row). Shown are the flux-limited (grey contour lines and data points) and dust-attenuated samples (coloured contours and data points). The columns and colour coding for different dominant ionising sources, the empirical selection criteria to distinguish between them and the SDSS-observed galaxies, shown for comparison, follow the same layout as Fig. 3.
